R-K Electronics, Inc. Protection Relays & Systems TVM-200-21-0002

The TVM-200 is a three-phase voltage relay for monitoring line voltages between 200 and 250VAC, with plug-in mounting and an 8-pin octal termination. It provides protection against overvoltage, undervoltage, phase loss, and incorrect phase rotation, with a fixed 0.5-second pick-up and drop-out delay. The relay output is rated at 10 amps at 250VAC, 1/2 HP at 250VAC, or 10 amps at 30VDC. It operates from 0°C to 40°C and includes a status LED. Weight is approximately 4.5 ounces, and it is packaged with a dust cover. For the 200 series, the over/under voltage window is set to 13% of nominal voltage.
